Similarly, the spraying direction of the nozzle 405 on the mounting ring 2 106 is opposite to the rotation direction of the mounting ring 2 106, and then the thrust sprayed by the nozzle 405 accelerates the rotation of the mounting ring 2 106, thereby increasing the rotation speed of the mounting ring 105 and the mounting ring 2 106, and improving the uniformity and cleaning efficiency of the inner wall of the coal mine filling pipe.

When in use, the main body 101 is placed in the coal mine filling pipe, the open end of the main body 101 is connected to the water pipe, and the other end of the main body 101 is connected to the traction rope. Under the guiding action of the arc-shaped slide groove 501, the tension spring 1 503 pulls the guide slider 502 to move, and the guide slider 502 drives the rotating arc rod 107 to rotate through the connecting rod 1 504, and the rotating arc rod 107 drives the protrusion 109 on the counterweight sleeve 108 to strike the inner wall of the coal mine filling pipe. The protrusion 109 squeezes the impurities attached to the inner wall of the coal mine filling pipe and crushes the impurities attached to the inner wall of the coal mine filling pipe. The water pipe fills the pipe 102 with high-pressure liquid, and the liquid in the pipe 102 passes through the through hole 1 403 and the through hole 2 404 respectively. The liquid enters the connecting ring groove 1 401 and the connecting ring groove 2 402, and the liquid in the connecting ring groove 1 401 and the connecting ring groove 2 402 is then sprayed out from the nozzle 405, and then the inner wall of the coal mine filling pipe is washed by water pressure, and the water flow in the pipeline 102 pushes the blade 202, and the blade 202 drives the rotating ring 201 to rotate, and the rotating ring 201 drives the outer gear ring 1 203 to rotate, and the outer gear ring 1 203 drives one of the transmission gears 1 207 to rotate, and one of the transmission gears 1 207 drives the rotating shaft 1 206 to rotate, and the rotating shaft 1 206 drives another transmission gear 1 207 to rotate, and the other transmission gear 1 207 drives the inner gear ring 1 205 to rotate, and the inner gear ring 1 205 drives the installation ring 2 106 to rotate, and the installation ring 2 106 drives the inner gear ring 2 304 to rotate, and the inner gear ring 1 205 drives the installation ring 2 106 to rotate. The gear ring 2 304 drives one of the transmission gears 2 306 to rotate, one of the transmission gears 2 306 drives the rotating shaft 2 305 to rotate, the rotating shaft 2 305 drives another transmission gear 2 306 to rotate, the other transmission gear 2 306 drives the outer gear ring 2 302 to reverse, the outer gear ring 2 302 drives the mounting ring 1 105 to reverse, thereby causing the mounting ring 1 105 and the mounting ring 2 106 to rotate in opposite directions, the mounting ring 105 and the mounting ring 2 106 drive the nozzle 405 to rotate, thereby evenly flushing the inner wall of the coal filling pipe, the mounting ring 105 drives multiple rotating arc rods 107 and the striking weight sleeve 108 to rotate, thereby causing the striking weight sleeve 108 to rotate on the inner wall of the coal filling pipe, so that the protrusion 109 can fully crush the impurities attached to the inner wall of the coal filling pipe When the mounting ring 105 rotates relative to the main body 101, the mounting ring 105 drives the rotating arc rod 107 to revolve, thereby causing the rotating arc rod 107 to rotate relative to the main body 101 and the L-shaped active push block 602. When the rotating arc rod 107 drives the passive push plate 601 to pass through the L-shaped active push block 602, the L-shaped active push block 602 pushes the passive push plate 601, and the passive push plate 601 overcomes the elastic force of the tension spring 503 and drives the rotating arc rod 107 to rotate, thereby causing the rotating arc rod 107 to drive the knocking counterweight sleeve 108 to move away from the inner wall of the coal filling pipe until the L-shaped active push block 602 is no longer in contact with the passive push plate 601, and the tension spring 503 pulls the guide slider 502 to move, and the guide slider 502 drives the rotating arc rod 107 to rotate through the connecting rod 504.The rotating arc rod 107 drives the striking weight sleeve 108 to strike the inner wall of the coal filling pipe, thereby crushing the impurities attached to the inner wall of the coal filling pipe, and the protrusion 109 on the striking weight sleeve 108 further improves the impact effect. The striking weight sleeve 108 strikes the inner wall of the coal filling pipe, thereby crushing the impurities attached to the inner wall of the coal filling pipe, and through the vibration of the coal filling pipe, the impurities attached to the inner wall of the coal filling pipe can also be shaken off, and the inner wall of the coal filling pipe is fully cleaned. Under the pulling force of the traction rope, the main body 101 is driven to move in the coal filling pipe, thereby cleaning the entire inner wall of the coal filling pipe.
